The invention relates to the technical field of circuit board processing, in particular to a pneumatic vibration main shaft for circuit board processing and a circuit board drilling method. The main shaft comprises a main shaft shell, a floating rotating shaft and a pneumatic vibration assembly. The pneumatic vibration assembly is provided with a first air pressure cavity and a second air pressure cavity which are oppositely arranged in the axial direction of the floating rotating shaft, and a first air path and a second air path which are communicated with the two cavities and can independently control air pressure. By controlling the air pressure of the two air paths, a controlled air pressure difference is formed between the two cavities, so that the floating rotating shaft is driven to generate axial reciprocating vibration. Axial micro-vibration of the drill point is achieved through the pure pneumatic principle, chip removal in the drilling process is effectively promoted, the hole wall quality and the drilling precision are improved, and the system is simple in structure and high in anti-interference capacity.

The utility model belongs to the technical field of woodworking tools, and particularly relates to a four-edge woodworking gang drill. The extension surface of the outer side surface of the cutting edge body defines a drill bit peripheral surface, the drill bit peripheral surface is of an inverted conical structure, and the cutting edge end of the drill bit is of an arc structure and is obliquely distributed on the drill bit peripheral surface; a cylindrical drilling machining face coaxial with the drill bit is formed at the end, away from the drill rod, of the drill bit, a drill bit auxiliary chip removal space is formed between the outer side face of the cutting edge body and the drilling machining face, the drill bit auxiliary chip removal space is communicated with an auxiliary chip removal groove in the drill rod, and the drill bit auxiliary chip removal space is gradually increased in the direction from the drill bit to the drill handle. One part of wood chips generated in the drilling machining process are discharged through the main chip discharging groove, and the other part of the wood chips are discharged through the drill bit auxiliary chip discharging space and the auxiliary chip discharging groove. Compared with the prior art that a spirally extending groove is formed in the cylindrical side face of the drill bit, the machining difficulty of grinding the peripheral face of the drill bit into the inverted-cone-shaped structure is lower. The machining difficulty of the drill bit is reduced on the premise that the good chip removal effect is guaranteed.
